Title: Cryogenic process for the separation of air to produce ultra high purity nitrogen
Inventor: AGRAWAL RAKESH
IPC: F25J3/04
Filed: 1991-12-27
Granted: 1994-11-01
Abstract: This invention relates to a cryogenic process for the separation of air utilizing an integrated multi-column distillation system wherein an ultra high purity nitrogen product is generated.  In the cryogenic distillation separation of air, air is initially compressed, pretreated and cooled for separation into its components.  Ultra high purity, e.g., nitrogen typically having less than 0.1 ppm impurities is generated in a multi-column distillation system comprising a first column and an ultra high purity nitrogen column with enhanced nitrogen product recovery by withdrawing a gaseous nitrogen fraction from a first column and charging that fraction as a feed to the ultra high purity nitrogen column, withdrawing a nitrogen stream which is rich in volatile contaminants from the top of the ultra high purity nitrogen column and recovering a nitrogen product at a point below the removal point of the nitrogen rich stream containing volatile components.  Removal of volatile components in the distillation process is effected by partially condensing a nitrogen vapor stream from either the first column or the ultra high purity column and removing at least one of the uncondensed portions of the nitrogen rich stream containing volatile components as a purge stream.

Title: System and method for precision cleaning by jet spray
Inventor: PETERSON RONALD V
IPC: B08B5/02
Filed: 1992-09-03
Granted: 1999-04-20
Abstract: A system and method for precision cleaning of contaminants from the surface of a substrate, such as delicate surfaces or precision parts, utilizing streams of carbon dioxide snow or other cleaning gas.   The system includes an enclosed or sealed cleaning container in which at least one jet spray device is housed for directing a stream of cleaning snow against the surface to be cleaned.  During cleaning, the cleaning container holding the substrate to be cleaned is maintained under a vacuum or, optionally, at ambient pressure, filled with a clean dry gas.  The dislodged contaminants and spent snow are removed from the cleaning zone and disposed of or  recycled.    Cleaning  is  accomplished  by  pulsed application of the cleaning snow in combination with intermittent or continuous heating of the surface so that the surface is at an elevated temperature prior to and during each application of cleaning snow.  The jet spray devices which are utilized in the system are oriented so that the  cleaning snow streams contact planar surfaces at grazing angles of 5 to 45 degrees. When non-planar parts are being cleaned, the jet spray devices are adjusted to provide an angle of about 45 to 90 degrees.  Monitoring of the cleanliness of the parts is accomplished during the cleaning process, by a light scatter method or by a particle monitor and residual gas analysis of the exhaust gas or other analysis of the exhaust gas.   The system is particularly useful in removing contaminants  from the delicate surfaces or precision parts which are utilized in precision optical and electronic devices.

Filed: 1993-06-03
Granted: 1997-01-07
Abstract: A patch panel which includes an array of connectors includes a panel plate (22) having an array of openings (24,24) formed therein. Each opening is capable of receiving an adapter (30) which may be made of a plastic material and which includes opposed depressible cantilevered beams. Each adapter on opposed top and bottom surfaces of the arms includes two wedge-shaped tabs which cooperate with depending portions of sidewalls of the adapter to secure the adapter to the panel plate. Opposed grooves (55,55) open to internal sidewall surfaces and terminate in bridge portions (58,58) adjacent to a rear of the adapter. Each groove is adapted to receive a resilient tab (68) formed in a sidewall of a connector (60) or detent member (97) of a collar (80) to be received in the adapter. When the connector or collar is seated fully in the adapter, the resilient tab or detent engages a forward surface of the bridging portion and collinear strips also formed on each sidewall of the connector or depending portions of the collar engage a rear surface of the bridging portion to secure the connector or the collar to the adapter. This arrangement allows any one of different types of connectors to be secured to the patch panel by securing the connector to an adapter which is secured to the panel plate. Rearrangements are made easily and may be made from the front or rear of the panel plate.
